A gene product thought to be involved in the downregulation of fetal hemoglobin expression is being investigated. Samples of primary tissue cultures of fetal, neonatal, and adult liver and bone marrow, as well as adequate amounts of a DNA probe believed to contain the studied gene, are provided. The best method for determining which of the tissue culture samples expresses the studied gene is
(A) DNA sequencing
(B) Northern blot
(C) Polymerase chain reaction (PCR)
(D) Southern blot
(E) Western blot
